It was called a Tach-vac manufactured by Westach. I don't see it on their website at this moment. Maybe JimK had a run of them made, but I don't see it on his website either.

The Birchaven came with one and I loved it. Before I installed the EBL I drove by it and it improved my driving MPG.
If you locate one please post who's selling it online.
Couldn't find it with a Google image search. Looks like there was some discussion back in '22: https://www.gmcmotorhome.org/threads/what-gauges-should-one-add.1616/
Perplexity AI drew a blank and I think it was starting to get annoyed with me!
"Based on my research and the automotive gauge market, there are virtually no mass-produced physical needle combination tachometer + vacuum gauge units available online. Here’s what you need to know:
Reality Check: Why These Don’t Exist as Single Units
-Tachometers require electrical RPM signal (from ignition coil); vacuum gauges need physical vacuum hose connection
-Manufacturers sell vacuum/boost combos (for turbos) but not vacuum/RPM combos
-Combining electrical + mechanical sensors in one analog housing is rarely done"
This is more evidence I'm an analog guy in a digital world.
This used to be a very very common item to buy/install. But they were none to cheap.. you paid for a item that fit the gmc well.
I see gmcrvparts shows a “tech vac 2). With rpm range to 5000 now.

I've learned the gauge is made by Pete Westberg Mfg Inc. He got back to me and is looking around to see if he has any. One thing is for sure: if he has it, it will be expensive.
A nice format for two guages that make a lot of sense together.
I have a large vacuum guage and tach in my custom dash bought by PO. I find vacuum info to be very helpful while driving.
I like them large but those shown would be a nice addition if you were tight on space.
